This means different things for the different type of interfaces + * we support. For a regular station this mean we add the AP sta when we + * receive an assocation response from the AP. For IBSS this occurs when + * we receive a probe response or a beacon from target IBSS network. For + * WDS we add the sta for the peer imediately upon device open. When using + * AP mode we add stations for each respective station upon request from + * userspace through nl80211. + * * Because there are debugfs entries for each station, and adding those * must be able to sleep, it is also possible to "pin" a station entry, * that means it can be removed from the hash table but not be freed. -- 2.20.1
